Parallel application I/O performance often does not meet user expectations. Additionally,
slight access pattern modifications may lead to significant changes in performance due to …

Modern, large-scale scientific computing runs on complex exascale storage systems that
support even more complex data workloads. Understanding the data access and movement …

The need for reliable and cost-effective data storage grows as digital information becomes
increasingly ubiquitous. Archival systems must store valuable data for years while adapting …

Data with vastly different access characteristics is efficiently stored in multi-tiered storage
systems. A cost-effective way to retain large volumes of infrequently accessed data is to …

Cold storage devices such as tape and optical discs are a good solution for reducing the
total cost of owner-ship for storing data. However, there is a drawback in that media and …

In September, 2018, the Department of Energy, Office of Science, Advanced Scientific
Computing Research Program convened a workshop to identify key challenges and define …

Long term retention of data has become a norm for reasons like compliance and data
preservation for future needs. With storage media continuing to become cheaper, this trend …

The importance of archival storage has increased with the growing demand for cost-effective
long term data storage. Existing storage technologies like tape, hard disk drives, and solid …

The metadata IO plays a critical role in achieving the high IO scalability and throughput to file
systems. Due to the resource contention, the performance of the metadata IO is low. Adding …

Disk drives have seen a dramatic increase in storage density over the last five decades, but
to continue the growth seems difficult because of physical limitations. One promising …
